They do! I think it is usually 10yrs or until it has been in a crash.

In the long term, modern child restraints and boosters in Australia typically have an expiration date — usually ten years after manufacture. While this isn’t enforced by law, it’s recommended you replace seats after they expire due to the risk of failure increasing as the materials in the seat degrade over time

Yes they do. I learned the hard way by keeping mine to pass on to a family member. I had taken extremely good care of it and thought it would make an excellent hand me down, unfortunately over the years all the foam broke down and it was unusable.

They surely do. The date should be somewhere on the device. Also second hand ones aren’t good if they’ve been involved in a car accident, do be careful

Yes they do. They should have a sticker at the back. Out of date car seats are not guaranteed safe.

10 years is the guide from date of manufacture (unless in an accident or damaged – in that case it must be replaced)

I didn’t know this, i will have to check mine to see if they are still alright

I think as long as they have not been involve in a car accident and all belts , structure is solid and not damage it can last a long time . That is why they recommend you buy brand new baby seats unless it is given by a very trusted source . If you can buy a new one from a dept store such as Kmart etc…

I think if they are involved in a car accident in any way , they must be thrown out . I haven’t heard anything else .

Yeah, they do. I found that out when I was given a second hand one for my son. I’m not sure what it is though

Yes they do.
You will find a sticker on the back of the car seat which will have the manufacture date &/or expiration date.
If it only lists the expiration date you should contact the manufacturer or check their website for details regarding expiration.
It is illegal to use an expired car seat I believe, but it is also very dangerous.
Please make sure when purchasing a car seat, or using one from a previous child, you do check that it is still within the expiration date.
These things are in place for a reason.

I kept a car seat packed away for 8 years and when I gave it to my sister to use and she unpacked it, the foam had totally disintegrated and had become a health hazard, so the seat could not be used.

I don’t think they do. I know if they’re second hand, you need to find out if they’ve been involved in a car accident, as that can affect their future performance. My brother gave me his car seat, I used it for my kids then passed it onto my niece fir her kids. She had 6 so it was pretty much wrecked by the time she finished with it and it wasn’t handed on again.

I think its about 7 years but I could be wrong

I thought it was between 5-10 years from the manufacture date

I know you can not on sell them and that the legislation probably changes but I am not familiar with a specific date- good question

I was told not to use it for longer than 4 years and if any cracks appear to stop using immediately

The foam ones can suddenly break without warning after about 3 or 4 years.
I always keep our seats covered with material if the car is going to parked outside for a few hours. The sun deteriorates them. The buckles of the harness can get hot very quickly if the sun goes on them, especially in warm weather.

10 years maximum. If they exposed to the sun or any other harsh elements I would destroy it and throw it out sooner.

We usually use as our rule of thumb that each car seat is only suitable for one child. When we are ready to hand it down, we take it to the RTA or local complying body to have the restraints reviewed and updated. It’s a quick and cheap matter to update the belts, and much more reassuring that constantly passing seats onto another child when the belts might be wearing away over time.
